The sodium and potassium in a sample
weighing 0.9250 g are converted into NaCl (58.44
g/mol) and KCl (74.61 g/mol) . The chloride
mixture weighs 0.6065 g. The chlorides are then
converted into Na2SO4 (142.04 g/mol) and K2SO4
(174.26 g/mol). The mixture weighs 0.7190 g.
Calculate the percentage Na2O (61.98 g/mol)
and K2O (94.20 g/mol) in the original sample.
Ans: 12.96% Na2O; 25.97% K2O
